The world's largest isothermal forging equipment developed by our institute successfully tested

On the afternoon of March 31, the 300MN isothermal forging hydraulic press developed by Tianjin High-end Equipment Research Institute of Tsinghua University (hereinafter referred to as "Tsinghua Tianjin High-end Institute") was successfully tested in Xi'an Triangle Defense Co., Ltd. (hereinafter referred to as "Triangle Defense"). This equipment is the world's largest isothermal forging equipment. The success of this hot test marks an important and solid step towards the development and production of key and important parts for large-scale die forging in aviation and aviation fields.

　　Zhang Lei, executive deputy director of the heavy equipment Technology Research Institute of Tsinghua Tianjin High-end Institute (hereinafter referred to as "heavy equipment Institute"), is in charge of the project. He said that the 300MN isothermal forging hydraulic press adopts the current international first-class design and control system, which will greatly promote the development and production of aviation aircraft and engine forgings. The main structure of the equipment has completely independent intellectual property rights, and adopts the "steel wire prestressed winding section-kanghe" technology independently developed by Tsinghua University. This technological achievement has won the second prize of national science and technology, and has been highly valued and cared by national leaders and successive leaders of Tsinghua University. The technology of "steel wire prestressed winding split-kanghe" breaks through the difficulties of design of super-large bearing frame and design and manufacturing technology of ultra-high pressure and super-large tonnage servo master cylinder, and has the characteristics of high stiffness, high fatigue and high precision.

Yan Jianya, Chairman of Triangle Defense, Guo Yingguang, General Manager, and Zhang Lei, Executive Deputy Director of the Heavy Loading Institute of Tsinghua Tianjin High-end Institute, jointly started the thermal test for the 300MN isothermal forging hydraulic press.

　　The 300MN isothermal forging hydraulic press uses a single master cylinder 8 balance cylinder layout and a single load-bearing frame structure layout, which is one of the best layout structures for forging and forming aviation precision die forgings. The core components such as the frame and the main cylinder adopt the steel wire prestressed winding technology to ensure that the main structure of the equipment has high rigidity and high reliability, and can effectively reduce the manufacturing cost and manufacturing difficulty. The equipment can achieve ultra-low constant speed and constant strain rate forging, equipment control accuracy, forging accuracy and other indicators to reach the world-class level. The completion and commissioning of 300MN isothermal forging hydraulic press can meet the needs of isothermal superplastic forming and precision die forging of difficult-to-deform alloy forgings such as aviation high-temperature alloys, titanium alloys and powder alloys, and play an important role in the independent innovation and independent manufacturing of large-scale die forging structural parts and precision disc shaft isothermal forgings.

　　The 300MN isothermal forging hydraulic press is another remarkable achievement made by Tsinghua Tianjin High-end Institute in scientific and technological innovation and achievement transformation with the innovation mission of "localization of independent innovation in the equipment industry and high value-added service industry" and talents as the link. The equipment can realize independent innovation in the field of aviation and aviation development, and has important strategic significance for improving the technical level of my country's aviation equipment. 2021 is the 100 anniversary of the founding of the Communist Party of China and the 110 anniversary of the founding of Tsinghua University. Tsinghua Tianjin High-end Institute successfully celebrated the 100th anniversary of the founding of the party with the thermal test of 300MN isothermal forging hydraulic press, adding color to the 110 anniversary of Tsinghua University, and contributing to my country's aviation and aviation development The take-off of the industry has made new and greater contributions to national development and national rejuvenation.
